  If your Mitsubishi Projector is displaying "NO SIGNAL", try these steps: * Ensure the connected device is powered on and functioning correctly. * Verify that the external device is outputting signals, especially if it's a notebook computer. * Check that the cable connecting the projector to the external device is not defective. * Confirm that the projector is connected to the external device using the correct terminals. * Make sure the connected device is correctly selected as the input source. * If using an extension cord, replace it with the supplied cable to see if that resolves the issue. If it does, use an RGB signal amplifier with the extension cord.

  If images suddenly disappear from your Mitsubishi Projector, consider these potential causes and solutions: * **Blocked Airflow:** The air inlet or outlet grille might be blocked. Remove any obstructions, then wait for the fan to stop (or the STATUS indicator to go out). Unplug the power cord, wait 10 minutes, plug it back in, and press the POWER button. * **Lamp Issue:** If the STATUS indicator is blinking red, it indicates that the lamp needs to be replaced.

Why images aren't projected on the screen with my Mitsubishi HC3 Projector?

  Tanya MillerAug 18, 2025
  There are several reasons why images might not be projecting correctly. Here are a few things to check: * Ensure the lens cap is removed. * The lamp may take up to a minute to light up, so be patient. * On rare occasions, the lamp might fail to light up on the first try. Wait a few seconds and try again. * If the projector was turned off before the lamp cooled, wait for the fans to stop before turning it on again. * Confirm that the filter is clean and the lamp cover is closed. * Make sure the cable connected to the external device isn't broken. * If using an extension cord, try the supplied cable instead. If that works, use an RGB signal amplifier with the extension cord. * Ensure that SCART INPUT in the FEATURE menu is set to OFF.
